中文说明：
雷达信号去斜处理方法：去斜处理(宽带的匹配滤波)Stretch方法是针对线性调频信号而提出的, 其方法是将输入信号与参考信号 (经适当延迟的本振信号, 延迟量通常由窄带信号测距结果估计出) 混频。
English Description：
Radar signal de skew processing method: de skew processing (broadband matched filter) stretch method is proposed for LFM signal. Its method is to mix the input signal with the reference signal (local oscillator signal with appropriate delay, the delay is usually estimated from the narrowband signal ranging result)
